The cooling fan racing is a symptom of a No Post state in the Motherboard. The Power LED and diagnostic LED indications would be helpful in resolving your issue. If the power LED is flashing Amber, the power supply is suspect, solid Amber points to the motherboard or something connected to it. The DIAG LEDs 1234 on the front or ABCD on the back give more specific information.

Initial Impression, is motherboard failure, post the DIAG and Power LED indications for more exact diagnosis

First, get a small Phillips head screwdriver, a credit card, and something like an egg carton to store all the screws you'll pull out. You'll also need something to clean the dust off the heatsink and fans--a can of compressed air is by far the best choice for this.

Note: READ ALL THE DIRECTIONS BEFORE YOU START. This is not an easy thing to do, especially your first time. Be careful. This is not a quick job either; I'd budget at least two hours of solid work, and it may take the whole afternoon.

Step 1: Shut the machine down, unplug it, and remove the battery. It might also be wise to back up your important data.

Step 2: Open up the cover on the bottom of the laptop where the WiFi card sits. Carefully unplug the antenna cables from this card.

Step 3: On the back of the laptop there should be several screws near the display hinge. Unscrew these and remove them. Then open the display all the way until it is flat. Use the credit card to help you remove the trim above the keyboard where the power button is located. This trim is held in by clips and will make several unnerving popping sounds when you pull it off. Just be careful and everything should work out fine.

Step 4: Unscrew the keyboard and carefully lift it up. Follow the ribbon cable on the bottom of the keyboard to where it connects to the motherboard. Unplug it (carefully!) and set the keyboard aside. Also unscrew the circuit board where the power button is located and remove that; it is also connected via a cable that needs to be unplugged. Also unscrew and unplug the speakers.

Step 5: Close the screen and turn the computer over. Unscrew all the screws on the bottom of the machine. There should be about 10-15, I think. Make sure to remove the screws stuck under the little rubber plugs along the front of the computer. A couple of these hold the hard drive in place; remove the hard drive. Under the hard drive there are a few screws in the case; unscrew those as well. Look around on the sides of the laptop; there may be a few screws on the sides as well. They need to come out too.

Step 6: Turn the machine back over and open the screen.Unplug the display cable and unscrew the four screws that hold the hinge on the display to the computer. Set the display aside. You may have to unscrew the little circuit boards near the hinges; those are the WiFi antennas.

Step 7: Remove all the screws in the metal plate underneath the keyboard. Also unplug any relevant ribbon cables that are connected to the motherboard and the top case (the palm rest part) of the laptop. The most notable of these is the trackpad connector, if you can get to it. You should also pull the wifi antenna connectors up through the machine now.

Step 8: Carefully lift the top case up, using the credit card to help you unsnap any clips holding it in place. Go slowly and don't force it because you may have missed a screw, either on the bottom or the top of the laptop. Also watch out for any connectors you missed. Remove the top case and set it aside.

Step 9: Unscrew the heatsink carefully. This is probably attached to the fan, so be careful. Also unplug the fan-but be VERY careful when you do this. Once I accidentally pulled the entire connector off and had to resolder it onto the motherboard. Take my word for it, that is not fun. Unscrew the fan, and you should be able to lift the heatsink and fan out to clean them.

Step 10: Follow these directions in reverse to put the machine back together. Go slowly and make sure you don't forget any screws or connectors. If you do, go back and find out where they go.

The first thing I would check is the power supply. It sounds like it has just enough power to turn on some lights, but not enough to power up fans, motherboard, CPU, etc. So either test the Power supply, or just purchase a new one. They are pretty cheap these days.

So basically you cannot get the pc to POST. Meaning you have just a black screen when you power on the pc, right?

First off, did you attempt to update BIOS before this happened. 90% of the time this is caused by a corrupt bios.

If you are the victim of a bad BIOS flash, don't freak there are some options. First off, if the computer (or motherboard) is still under warranty the Computer (or motherboard) can be sent to the Vendor for a BIOS reprogramming. If you are a DIY PC builder and the warranty is expired you can take out the bios chip and sent it someone who reprograms BIOS chips or you can buy a brand new chip form them. I will show you my people.

For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen.

This fan error message shows up when the CPU fan is not plugged into the CPU FAN plug on the motherboard. The Intel D865GVHZ motherboard has a total of 4-fan plugs so it is easy to plug the CPU fan into one of the other fan plugs that is not marked CPU FAN on the motherboard.

Normally the computer will still come on even if the fan is not there but then will sometime display cpu fan warning and then sometimes turn off depending on motherboard and so on but unless the fan wires are shorted out or something this is most likely not the case It sounds like your power supply has gone bad Do you hear any type of winning sound or like a discharge sound that is barely noticeable when you turn it on? You would probably almost have to put your ear right next to it to hear it or listen carefully when you press power because that sound is one of the capacitors in the power supply that has gone bad and the power supply would need to be replacedDo you have another power supply you can use to see if it works with a different one?
